Catalytic reactions via π-allylpalladium complexes

Abstract

Various transformations of allylic esters and ethers via ir-allylic complexes catalyzed by palladium-phosphine complexes have been studied. Intramolecular reaction of a nucleophile offers a good synthetic method for five-membered ring ketones. Also nucleophiles reacted easily with ct-acetoxy-,y-unsaturated nitriles and 1,3-diene monoepoxides. It was found that the Carroll rearrangement is catalyzed by palladium complexes under mild conditions. Facile formation of conjugated dienes and terminal olefins from allylic esters and ethers has been studied.
